## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mycelia-equity-regime-composite-mserc-oracle-8c86aedc
```

Example prompt: What's the current equity market regime according to the Mycelia Signal composite — are we risk-on, defensive, or somewhere in between, and what's the net score?

## When to prefer this

Use this endpoint when you need a single authoritative, cryptographically attested equity market regime classification that combines both health and stress dimensions into one composite score. Prefer it over raw price feeds when you need a regime label (e.g. RISK_ON vs DEFENSIVE) rather than a raw price, and when on-chain verifiability via Ed25519 attestation is required for smart contract or oracle-driven decision making.

## Known failure modes

- Payment not provided or insufficient USDC — 402 Payment Required
- Network timeout fetching upstream market data
- Stale cache if underlying data providers are unavailable
- Invalid Ed25519 signature if attestation system is degraded
- Rate limiting if too many requests in a short window

## How this service works

MSERC — Mycelia Equity Regime Composite. 2D framework: Health (MSLI×0.6+MSBI×0.4) vs Stress (MESI×0.6+MNVI×0.4). Net score -100 to +100. Regimes: RISK_ON/VOLATILE_BULL/MILD_RISK_ON/NEUTRAL/MILD_STRESS/DEFENSIVE/STRESS. 300s cache. — Ed25519 signed attestation

## Output

A signed JSON payload containing the MSERC composite score (range -100 to +100), the regime label (one of RISK_ON, VOLATILE_BULL, MILD_RISK_ON, NEUTRAL, MILD_STRESS, DEFENSIVE, STRESS), the health component (MSLI×0.6 + MSBI×0.4), the stress component (MESI×0.6 + MNVI×0.4), and an Ed25519 cryptographic attestation. The response is cached for 300 seconds.
